Pre Start-Up Checklist
†Disconnect and lock-out all power switches.
† Remove any foreign objects that are located in the
energy recovery unit.
† Check all fasteners, set-screws, and locking collars
on the fans, bearings, drives, motor bases and
accessories for tightness.
† Check fan rotation.
† Rotate the fan wheels and energy recovery wheels
by hand and ensure no parts are rubbing.
† Check the fan belt drives for proper alignment and
tension.
† Filters can load up with dirt during building
construction. Replace any dirty pleated filters and
clean the aluminum mesh filters in the intake hood.
† Verify that non-motorized dampers open and close
properly.
† Check the tightness of all electrical wiring
connections.
† Verify control wire gauge.
† Verify diameter seal settings on the energy recovery
wheel.
† Verify proper drain trap installation.
† Check condensing fans for any damage or
misalignment. Spin the blades and make sure they
don’t contact any parts and are free-turning without
any resistance.
† Look over the piping system. Inspect for oil at all
tubing connections. Oil typically highlights a leak in
the system.
† Inspect all coils within the unit. Fins may get
damaged in transit or during construction. Carefully
straighten fins with a fin comb.
† If there is an indirect gas-fired furnace in this unit,
refer to the manual provided with this unit for Pre-
Start-Up information.
† This unit contains a crankcase heater for each
compressor which needs power supplied to it
24 hours prior to start-up. If start-up is scheduled
in 24 hours, unlock the disconnect power and
energize unit.
